S0, S0, S0 SERIES SPRING RETURN DIRECT COUPLED S Sizing Required Torque In lieu of data from a Specification Engineer or Manufacturer, required torque for a given damper load can be determined using the following method: T R = T D A D Where: T R = Required torque for the damper load. T D = Damper torque rating from the manufacturer, expressed in either (lb-in.)/(sq ft) or (N m)/(sq m). the damper load. A D = Damper area expressed in either sq ft or sq m. Actuators Required In lieu of data from a Specification Engineer or Manufacturer, the number of required actuators for a given damper load can be determined using the following method: T R N = ------------------ Where: T A SF N = Number of actuators. T R = Required torque for the damper load. (See above.) T A = Actuator torque rating. SF = Safety factor. The safety factor accounts for variables such as misalignments, aging of the damper, etc. 0.8 is a typical safety factor. INSTALLATION When Installing this Product.... Read these instructions carefully. Failure to follow them could damage the product or cause a hazardous condition.. Check the ratings given in the instructions and on the product to make sure the product is suitable for your application.. Installer must be a trained, experienced service technician.. After installation is complete, check out product operation as provided in these instructions. CAUTION Electrical Shock or Equipment Damage Hazard. Low voltage can shock individuals or short equipment circuitry. Disconnect power supply before installation. NOTES: When mounted correctly, these slots allow the actuator to float without rotating relative to the damper shaft. Using other brackets or linkages, the actuator can be foot-mounted or tandem-mounted. CAUTION Motor Damage Hazard. Deteriorating vapors and acid fumes can damage metal parts. Install motor in areas free of acid fumes and other deteriorating vapors. CAUTION Equipment Damage Hazard. Tightly securing actuator to damper housing can damage actuator. Mount actuator to allow it to float along its vertical axis. Preparation Before mounting the actuator onto the damper shaft, determine the: Damper/valve opening direction for correct spring return rotation. The actuator can be mounted to provide clockwise or counterclockwise spring return. Damper shaft size (see the Specifications section). Determine Appropriate Mounting Orientation The actuators are designed to open a damper by driving the damper shaft in either a clockwise or counterclockwise direction (see Fig. ). NOTES: Actuators are shipped in the fully closed (spring return) position. An arrow molded into the hub points to tick marks on the label to indicate the hub rotary position. CCW TO CLOSE (FAIL-SAFE POSITION) CW TO OPEN CW TO CLOSE (FAIL-SAFE POSITION) CCW TO OPEN IMPORTANT All wiring must agree with applicable codes, ordinances and regulations. Location These actuators are designed to mount directly to a damper external drive shaft. The shaft coupling fastens to the drive shaft. The actuator housing includes slots which, along with an anti-rotation bracket, secure the actuator to the damper frame or duct work (see Fig. 8). M09 Fig.. Spring Return DCA mounting orientation. Measure Damper/alve Shaft Length If the shaft is less than three inches in length, the shaft coupling must be located between the damper/valve and actuator housing. If the shaft length is more than three inches, the shaft coupling may be located on either side of the actuator housing. 6-607 08
S0, S0, S0 SERIES SPRING RETURN DIRECT COUPLED S If the coupling must be moved from one side of the actuator to the reverse, follow these instructions (see Fig. ):. Remove the retainer clip from the shaft coupling and set it aside for later use.. Remove shaft coupling from one side of the actuator.. Replace the shaft coupling on the opposite side of the actuator aligning it based on the stroke labelling.. Replace the retainer clip on the shaft coupling using the groove of the coupling. Enhanced: includes different mode selection dial to select the desired input signal. Also includes dials for adjusting the input signal zero and span.

Non-Standard Stroke Mechanical Stroke Limit Reduction For applications requiring a span less than 9 degrees, a simple adjustment can be made. When the rotational mounting of the shaft coupling is changed, the actuator drives less than the full 9 degrees stroke. The stroke is adjustable in degree increments. Once adjusted, the actuator drives until the shaft coupling reaches the mechanical stop (part of the housing). The stop causes the motor to discontinue driving and the shaft coupling drives no farther. When the actuator returns, it stops at the fail-safe position. To set the fail-safe position, proceed as follows:. Remove the retainer clip from the shaft coupling and set it aside for later use.. Remove shaft coupling from the actuator.. Rotate the coupling to the desired fail-safe position, aligning it based on the stroke labelling. See Fig.. 6-607 08
S0, S0, S0 SERIES SPRING RETURN DIRECT COUPLED S The shaft coupling location determines the travel span. EXAMPLE:Setting shaft coupling to an approximate fail-safe position of degrees (as indicated on the housing) limits stroke to 60 degrees. (See Fig. ). Install the shaft coupling at this position.. Replace the retainer clip on the shaft coupling using the groove of the coupling. 6. If necessary, replace the holder and position indicator on the shaft coupling. 90 DRIE SPRING RETURN 90 STROKE 0 Fig.. Stroke reduction. Adjustable Zero and Span (Enhanced Modulating Models only) These actuators have the capability of adjustable zero and span. Fig. shows the dials. These dials are present only on the Enhanced Modulating models. A basic description of these dials follows: Zero: Sets input voltage to define the 0% angle of rotation. It is factory set to 0 dc, and can be adjusted up to 0 dc. Span: Adjusts motor response to travel full stroke through the selected input span. It is factory set to 0 dc, and is adjustable from to dc. 90 DRIE SPRING RETURN 60 STROKE 0 M06. Rotate actuator control signal dial to Auto-Adapt. The actuator will drive open, then closed to establish the new open and closed positions.. Return the actuator control signal dial to the desired input signal position. Manual Positioning The actuator can be operated with no power present. Use this feature during installation or to move and lock the damper or valve shaft position when there is no power. To operate the manual positioning:. If the power is on, turn it off.. Insert supplied hex wrench (key) as shown in Fig. 6.. Rotate key in the direction indicated on the cover.. Once the desired position is reached, hold the key to prevent the spring return from moving the actuator.. With the key held in place, use a screwdriver to turn the gear train lock pin in the indicated direction until the detent is reached. At the detent, the pin resists further rotation. 6. Remove the key without rotating it further. To release the manual positioning with no power present:. Insert supplied key.. Turn key / turn in the direction indicated on the cover.. Remove key without engaging the gear train lock pin.. The spring will return actuator to the fail-safe position. 9 Once power is restored, the actuator will return to normal automated control. SET ADJUSTABLE ZERO AND SPAN. Apply ac to the actuator.. Turn the zero dial (see Fig. ) past the desired start point.. Using either a controller or signal generator, apply an input signal equal to the start point signal.. Slowly adjust zero toward the minimum setting until the actuator hub begins to move.. Turn the span dial (see Fig. ) to the minimum setting ( dc). 6. Using either a controller or signal generator, apply an input signal equal to the desired end point signal. 7. Allow the actuator to open fully. 8. Slowly adjust span toward the maximum setting until the actuator hub moves slightly from fully open. 9. Carefully adjust span knob toward minimum until the actuator hub returns to fully open. Auto-Adapt When using these actuators for standard stroke applications, this function can be ignored. When it is desirable to use a mechanically limited stroke (see Mechanical Stroke Limit Adjustment section), it is possible to use the Auto-Adapt feature to rescale the input signal over the new limited stroke.

S0, S0, S0 SERIES SPRING RETURN DIRECT COUPLED S OPERATION The actuator is designed to be used in ventilating and air conditioning installations to operate valves, dampers, ventilation flaps and louvers requiring torque up to the rating. (For ratings, see the Specifications section.) If the power fails, the actuator will spring return to the start position. The actuator is operated by a proportional controller. When using a proportional controller, the actuator drives toward its fully open position when the input signal increases; the actuator drives toward the fully closed position when the input signal decreases. The actuator stops when the input signal reaches the desired proportional control point. IMPORTANT The actuator is designed to respond to DDC Controller instantaneous contact closures. Take care not to short cycle the actuator. Unstable damper control can cause premature actuator failure. Actuator Override To override the control signal (for freeze protection or similar applications):. Override to full open: a. Disconnect the input signal (from terminal ). b. Apply ac to terminal. c. See Fig. 7.. Override to full closed: a. Disconnect the input signal (from terminal ). b. See Fig. 8. 0/ TO 0 DC PROPORTIONING AC Fig. 8. Override to full close.
